It carries 64 KB of program Flash, 4 KB of RAM, and 2 KB of EEPROM — enough for moderate firmware images and data logging in battery-operated or thermally demanding applications. ## Peripheral set: 25-channel ADC and dual DAC reduce external count The 41 I/O lines, plus I²C, SPI, USART, and IrDA connectivity, cover common serial buses for display, memory, and radio modules. ## Package and thermal path for extended-temperature designs For dual-sourcing resilience, the STM8L151C6U3 (32 KB Flash variant) is pin-compatible across the same package and temperature grade — a straightforward drop-in if the firmware fits the smaller memory.","metaTitle":"STM8L151C8U3 8-bit MCU, 16 MHz, 64 KB Flash, -40 to 125 °C","metaDescription":"STMicroelectronics STM8L151C8U3, STM8L EnergyLite series, 8-bit STM8 core at 16 MHz, 64 KB Flash, 4 KB RAM, 2 KB EEPROM, 41 I/O, 25-ch 12-bit ADC, 2-ch 12-bit","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"STM8L EnergyLite","Package":"Tray","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, IR, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"41","Core Processor":"STM8","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 25x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a42de1f8ef43937cd9450668e2e90014.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L151C8U3/alternatives.json"},"ai":{"faq":[{"question":"Can STM8L151C8U3 replace STM8L151C6U3?","answer":"Yes, the STM8L151C8U3 is pin-compatible with the STM8L151C6U3 in the same 48-UFQFN package.
